    getText() for me in the element class returns the element's name and not the
contents. Same problem with getAtrribute(name). I do not get a null string. I have
this happen when using both beta4 and beta5.

    To answer your question I would rather see return an expty string otherwise we
would alway's have to check for a null reference which could be tedious.
